IMPROVEMENT IN ROLLS FOR UTILIZING THE FAG-ENDS OF STEEL RAILROAD-RAILS.

Specification forming part of Letters Patent No. 215,065. dated May 6,1879; application filed July 1, 1878.

To all whom it may concern:

Be it known that I, MALCOLM MCDOWELL, of Chicago, Cook county, Illinois,have invent-- ed a newand useful Improvementin Rolls for Utilizing theScrap or Fag Ends of new Steel Railroad-Rails or the-Scrap of Old SteelRails in the manufacture of double-flanged plowheam shapes or billets,which improvement is fully set forth in the following specification,referencebein g had to the accompanying drawin gs.

Referring to the drawings hereunto appended and making part hereof, A B,Figure 1, represent a pair of cast-iron rolls, having the usualhousings, and to have the customary couplings and gearings to connectthem with the motive power.

1, 2, 3, 4, 5, 6, 7, and 8 are the grooves'or passes, through which, inthe order named, and when the rolls are in suitable motion, the heatedscrap or fag end of the steel rail or piece of scraprail is made topass. These grooves or passes are of such form, dimensions,andproportions as, when the scrapend. is "drawn through them, will upsetand at the same time elon gate the neck or web of the railend, compressand draw out the head and foot of it, and at the same time transfer aportion of the metal offithe head and foot into the neck orweb,concurrent1y with elongating and 11psetting the-latter, and all thisin such wise as to transformthe rail-end, as shown at Fig. 2, into adouble-flanged plow-beam shape or billet ot the desired dimensions andproportions, as shown at Fig.3.

I am aware of the patent granted John P.

Verree and William A. Mitchell, of Philadelphia, Pennsylvania, (No.65,968, of June 18, 1867,) for improvement, in rollers for rolling oldrails, and of the patent granted Henry Chisholm, of Cleveland, Ohio,(No. 124,116, of February 27, 1872,) for improvement in rolls forutilizing the fag-ends of railroad-rails. In each case the thing to bemade is a bar or rod for general purposes--in the case of the former abar or rod of iron made by lapping or folding inward the edges or sidesof the flange (foot) of the rail, and in the latter a bar or rod made bycompressing and rolling the head, neck, and foot (flange) of therailend, so as not to lap or fold into each other during the progress ofconversion to a bar or rod, thus securing a uniform bar or rod withoutseams or flaws.

I disclaim both the foregoing, my object not being to produce a bar orrod, either auniform one without seams or flaws, or otherwise, but totransform one irregular-shaped piece of steel into anotherirregular-shaped piece for a special purpose.

I do not confine myself to the exact outline or proportion of thegrooves or passes, or the invariable succession in their use, as theymay have to be varied to suit the difl'erent sizes and shapes of the fagor scrap ends; and as it may be desirable in certain cases to slit awaya strip from each side of the foot, in stead of compressing and drawingthe whole of the metal of the foot into the required shape or billet,provision is made at X to pass the fag-end through a groove to cut elfsuch portion of the sides or edges of the foot as may be foundexpedient.

I do not claim the mere form of the doubleflanged shape, as shown atFig. 3.

I claim The rolls A B, with their systemof grooves or passes, of theform, proportion, and relation described and shown herein, substantiallyas and for the purpose set forth.

MALCOLM MCDOWELL.
